'SHACKLE-IRON FOR WHIFFLETREES.

SPECIFICATION forming part of Letters Patent No. 251,140, dated December20, 1881.

Application filed September 17, 1881. (ModeL) To all whom it may concernBe it known that I, WILLIAM R. ScoFrELD, of De Wittville, in the countyof Chautauqua and State of New York, have invented a new and usefulImprovement in Shackle Irons for Whifflctrees; and I do hereby declarethe. the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to theletters ofreference marked thereon.

Figure 1 represents my improvement attached to the end of a whiflietree.Fig. 2 is a transverse section of the same, taken at linear aof Fig. 1'.Fig. 3 represents acentrallongitudinal section of the detachablehinge-connection, taken at line 3 y. Fig. 4. represents the D-shapedhinge-connection and ferrule or socket as attached to the center of awhiffletree.

Myimprovementrelatesto the mannerofconstructing and connecting thepartsof shackleirons for whiffletrees, and provides the means forreadily removing a worn and weak part and substituting a new partwithout mechanical aid or assistance, as hereinafter described.

Shackleirons for whifiletrees are usually forged and welded, theD-shaped loop I) being made as a part of ferrule 13. The chain or tracebook being connected ith loop D, as seen in Fig.1, by constant abrasioncauses loop D to be worn away, so as to be no longer safe for use,whileits ferrule embracing the whiffletree remains unimpaired, andconsequently when the loop D and ferrule B are formed as a single pieceboth must be cast aside and a new mounting substituted, although theferrule remains perfectly good. Such is also the result from wear of theloop I, connected with the hook, and for this reason I have provided thesecond small loop, H, which, when it becomes too much worn to be safelyused longer,

may be cutoff from loop I and the latter be used in its stead, inconnection with anew loop, D. The screw-bolt a and thimble O furnish themeans and ready facility of making the substitution above specified, theobject of my invention being to utilize all the parts of the shackleuntil each becomes too much worn to serve the purpose intended.

In the drawings, A denotes the whiffletree; B, the collar or ferrule; O,thethitnble orhingesocket, which is cast with ferrule 13; D, the loop,connected by the hinge-bolt ato thethimbleO; and E isthe hook prov dedwith the two loops H I, and as each of the parts-namely, the hook withits two loops, the hinge-loop D, and the ferrule B, with its thimbleO-may be cast of malleable iron the shackle-iron is cheapened inconstruction, and economy is at taiued by the means of supplying a newpart for one which has become trail and worthless, without having tocast asidea part still unimpaired.

Havingdescribed my invention. I claim and desire to secure by LettersPatent 1. The combination of the thimble-heating (3, cast as a part ofthe ferrule B, with the shackle-loop D, substantially as and for thepurpose herein specified.

2. The combination of the thimble-bearing 0, cast as a part of theferrule B, shat-ke-loop D, and the pivot-bolt a, screwed into thebearing 0, substantially as and for the pur; ose herein specified.

3. The combination of the thimble-beating G, removable shackle-loopl),and double loops H I, formed on the hook E, substantially as and forthe purpose herein specified.
